我有一个搜索功能（car_search.php），它允许用户选择汽车类型，年份和颜色，并指向搜索到的汽车的页面。如果他从搜索页面中选择了该页面，我如何将用户引导至Toyota Highlander 2012页面？
car_search.php

答案 0 :(得分：0)
你以正确的方式行事，但在你的if clausule中错误输入 $ type_car $ tape_car 。
另外作为建议你应该创建一些集合，一个用于汽车，一个用于多年，一个用于颜色而不是试图通过它们的名称设置作为选择参数的选项进行比较，这根本不可靠。
由于您似乎正在编写程序编程，我建议您将此表单和逻辑保存在同一页面中以便于维护，您可以选择 car_module.php 之类的名称并尝试此代码
